A Troubling Case, Even With Guilty Verdict

A United Kingdom jury has found a former British Airways employee guilty of using his job to prepare terrorist attacks, an alarming instance of terrorists infiltrating a major international airline.

The case of Rajib Karim, a Bangladeshi national who was found guilty of plotting with radical cleric Anwar al-Awlaki of al Qaeda in the Arabian Peninsula, does raise the question of whether he was the only one inside an airline planning terrorism attacks.

According to my colleague Cassell Bryan-Low, who reports from London, prosecutors there said Mr. Karim was engaged in a “chilling plan’’ to use his job at British Airways, where he was a software engineer, to blow up a passenger plane. On Monday, a jury found him guilty of four terrorism-related counts.
